With millions of dollars being invested in adult rural leadership development, it is essential that research be conducted to determine the effectiveness of this investment. Such research can validate the investment and provide guidance for future programming. However, an extensive review of literature in Cambridge Scientific Abstracts yielded only 15 relevant research articles over a decade of publication. Among these articles, sub-topic areas identified included Partnerships, Political Shifts, Safety & Health, Gender Equity, Public Discourse, Statewide Program Impact, and Continuing Education. All of these areas lacked adequate saturation of research. The effectiveness of rural leadership development is severely threatened by this lack of published research. With increasingly limited resources, those engaged in rural leadership development programming must address significant deficiencies in the research and share findings for the betterment of all.
